PATENT OFFICE JOSEPH srAsINsxI Am) HANS GROTEWOLD, or PEILADELIHIA, rmmsYLvAm Application filed June 8, 1928. Serial No. 283,807.

This invention relates to an improved automatic regulator for use in connection with the narrowing mechanism on knitting machines, particularly the full-fashion type of machlne, said regulator also including a stop mechanism.

In operating a full fashioned hose knitting machine of the type put out by the Textile Machine Works at Reading, Penna, it is the duty of the operator to determine the proper time to put the narrowing mechanism (shown on page 46 of the book disclosing the full fashioned knitting machine of the Textile Machine Works) into operation.

In the prior'art, namely the book published by the Textile Machine Works, the fashioning mechanism on page 46 includes a pattern chain, but in using said fashioning mechanism on page 46 of said publication, in connection with applicants invention, the pattern chain is eliminated.

Ifn operating the fashioning mechanism on page 46 of said publication, rotation is imparted to the cams wand b, which efiect a lateralshifting'movement of the start and stop cam shaft m of the fashioning mechanism shown to the right in Figure 1.

It is the'purpose of the present invention to provide a narrowing mechanism regulator automatic in its operation, from the beginning of the knitting ofthe hose until the completion of the hose. In connection with this narrowing mechanism regulator. it is the aim to first predetermine the number of courses to be in hose, there being a plurality of, sets of pattern and ratchet wheels corresponding .to hose varying in courses. Another purpbse is to provide a regulator of this character for use in connection with the narrowing mechanism on a hose knitting machine preferably of the full-fashion type, with means connecting a movable member of automatically actuate the narrowing mechanism according to the number of courses on the pattern wheel and according to the number of teeth on the ratchet wheel, it being obvious that the courses on different pattern narrowing mechanism from the time the fullfashion knitting machine is started until it completes the knitting of the hose, without at any time stopping the knitting machine, unless there is break in the thread or unless the machine is otherwise unavoidably stopped.

It is to be understood that the particulars herein given are in no way limitive, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

Re erring to the drawings, 1- ldentifies the base of the frame 2 of the narrowing mecha- IOU nism regulator, and j ournaled in suitable bearings of the uprights of'the frame 2 is a shaft 3 to be driven by a spur gear 4 (Fig. 3), which is designed to mesh with a sunilar spur gear 5 shown in dotted lines, Fig. 3, as mounted upon a power shaft 6 shown in dotted lines, Fig. 3, of a knitting machine of the full-fashion type. The spur gear 4 is loose upon the shaft 3 and is held against axial movement by a collar 7 secured upon the shaft 3 by a suitable set screw 8 (Figs. 2 and 5). Integral with one face of the spur gear 4 is a shoulder,

or boss 81; having a clutch tooth 9. A bracket 10 is bolted or otherwise fixed to the end face of one of the uprights of the frame 2, and pivotally mounted upon the bracket at 11 is a'lever 12, the forks 13 of which straddle a clutch sleeve 14 which is keyed at 14a to the shaft 3 as shownin Figs. 2, 3 and 5. This clutch sleeve has an annular groove 15 in which the shoes 16 operate. These shoes in Figs. 2, 3 and 5 are pivotally connected to the forks at 17, so that by tilting the lever 12 in one direction the clutch sleeve will move toward the shoulder or boss 8a with its tooth 9, and a movement of the lever 12 in the opposite direction will move the clutch sleeve awfiy from the boss or shoulder 8a.

ounted. in a flange 18 of the clutch sleeve is a clutch pin 19, which has a cotter pin 19a mounted transversely therein to limit the (letent or clutch pin 19 in one direction, that is a direction toward the boss or shoulder 8c (Fig. 5)

An angle plate 20 is carried in any suitable manner on one face of the flange 18, and interposed between one end of this angle plate and the clutch pin is a coil spring 21, which fits into the clutch pin, tending to move it in a direction toward the boss or shoulder 8a, being limited in this direction by the cotter pin, the spring behind the clutch pin acting to hold the cotter pin against the face of the flange (Figs. 2, 4 and 5). This spring tensioned clutch pin, the instant the clutch lever is operated to throw the clutch sleeve, provided the single tooth is not opposite the end of the clutch pin, will slide over the face of the shoulder or boss, until the tooth reaches the clutchpin then due to the fact that the gear 4 is drlven by the gear 5, revoluble movement will be imparted to the shaft 3 as may be understood from Figs. 2, 4 and 5. Mounted on the shaft 3 loosely is a clutch collar-22 with a clutch tooth 23 on one face and provided on its exterior circumference at a point aligned with the tooth is a stop lug 24, which is in the form of a screw (Figs. 2 and 4). Also mounted upon the shaft 3 is a clutch sleeve 25, fixed to the shaft by means of a set screw 26. This clutch sleeve has an annular groove 27, in the bottom of which the set screw 26 is seated.

Mounted on the base of the frame is a support 28, and carried thereby as shown clearly in Figure 3 is a solenoid 29 of conventional form provided with a core 30, and pivoted between forks 31 at the upper end of the sup-- clutch pin 33 is mounted in a socket 34 under tension of a spring 35, the clutch pin when released, designed to move longitudinally of the clutch sleeve, so that its extremity may fall in the path of the clutch tooth 23 of the clutch collar 22, due to the action of the coil spring 35, thereby clutching the collar 22 with the clutch sleeve (Figs. 2 and 4). The clutch pin 33 has a notch 36' in which the arm 32 engages, to hold the clutch pin 33 out of engagement with the clutch tooth 23.

Obviously when the solenoid is energized the core moves upwardly, thereby tilting the arm 32, moving it out ofengagement with the notch 36, and due to the action of the coil spring 35, the clutch pin 33 is moved in the path of the clutch tooth 23, whereb the collar 22 will move with the clutch s eeve 25, which is rotatable with the shaft 3.

A lateral arm 37 is secured to the arm 32 at 38 as shown in Figure 2, and the extremity 39 of the arm 37 rides on the exterior surface of the clutch collar 22 in the path of a stop lug or screw 24 shown in Figures 2 and 4. As it is necessary that the lateral arm 37 be raised out of the path of the stop lug or screw 24, in order to permit the release of the clutch collar 22, so that it can move, the raising of the arm 37 as well as the arm 32 is accomplished through the medium of the solenoid 29. When the arm 32 is lifted, it allows the clutch pin 33 to ride on the circular face of the clutch collar 22 in the path of the clutch tooth 23 shown in Figure 4 thereby stopping the clutch collar 22 after the clutch collar 22 has made one complete rotation. However when the arm 32 is raised through the medium of the core of the solenoid and with it the arm 37, the extremity 39 of the arm 37 is moved out of the path of the stop lug or screw 24 permitting the clutch collar to rotate with the clutch sleeve 25 and the shaft 3.

The clutch collar 22 has a lateral cam lug 43 (Fig. 5) projecting from one end face of the collar, and pivoted on a bracket 44 at 45 is a lever 46, which has a roller 47 mounted at 48 on one end of the lever (Fig. 5). A stop lug 49 is mounted on the bracket 44 (Fig. 5) and cooperates with the lever 46'for limiting the roller end of the lever 46 in a direction toward the clutch collar 22. The roller 47 lies in the path of the cam lug 43, and when the clutch collar is rotated with the shaft 3 the cam lug 43 moves against the roller 47 and tilts the lever 46 in the direction of the arrow 04.

Thislever 46 haspivoted to its lower end a rod 50, which in turn is pivotally connected to the lever k2. When the rod is moved ina direction of'the arrow a4, the lever k2 is tilted and the narrowing mechanism similar to that shown on page 46 in the catalogue of the Full Fashioned Knitting Machine-Textile Machine Works, Reading, Pa., 1920, operates in the usual manner, without the use of a pattern chain. Therefore the narrowing mechanism disclosed to the right in Figure l and which is similar to that shown on page 46 of the F nil-Fashioned Knitting Machine publication hereinbeforementioned is construoted and operates as follows: When the machine is changed to narrowing, the roller of which is kept out of reach of the cam a by means of a locking device, is released and brought within its reach by the pull of a spring n, so that the lateral projection d of the cam a will move against the roller 0 and as the latter is firmly held sidewise by its arm 'w will enforce the entire cam shaft m to shift to the right thereby move the knitting cams out of, and the narrowing cams into, action, Figure 1. After the narrowing has taken place the supplementary cam e,

fastened to a and working against f, pushes the latter back again and with it the arm w and roller 0. The roller 0 is thus brought into the path of a lateral projection g of cam b, and operates to shift the cam shaft m back to its original position. A rocking device rocks the arm or lever-w until another reverse movement of the cam shaft m is called for, as may be understood by referring to Figure 1 of the drawings. This device consists of a bellcrank lever having an arm k2 constantly pressed against a lateral projection it of the arm or lever to by means of its weighted other arm 72.. When the arm or lever w is in its normal position a shoulder at (12 engages projection 70 so as to prevent the lever or arm to from being shifted to move the cam shaft'm as described until the; lever or arm w is released. The lever46 (Figs.

1 and 5) is held in its limited position against the stop lug 49 by means of a tensioned spring 51, which connects the lever 46 and an arm 52 which is secured to the bracket 44, the bracket being carried in any suitable manner by one of the uprights of the frame 2.

Supported upon lateral lugs 53 and 54 of the upper ends of the end uprights of the frame 2 is an auxiliary frame 55, and rising from one end of the frame ,55 (Figs. 2, 3, 5 and 6') is a bracket 56 in a bearing 57 on the upper end of which is a shaft 58, which c arries a ratchet wheel 59, partly shown in full and dot and dash lines in 5.and in edge view- Figures 3 and 6';

The shaft'58 also carries with it a pattern wheel 44, shown in dot and dash lines in Figure 5 and in edge view in Figure 3 and 6, in side view in Figure 1, and in the plan view in Figure 2."

acting to operate the circuit closer or switch 42 for intern ittently closing the circuit to the solenoid i9, by which the arm 32 may be actuated to remove its extremity out of engagement with the notch 36, which allows the clutch pin 33 to move in the path of the tooth 23 of the clutch collar 22, so that the collar, clutch sleeve 25 and the shaft 3 may rotate as a body (Figs. 3, 5 and 6).

Rising from one end of the frame 55 is a standard having its upper end slotted at 66 to receive a bolt 67 by which a plate 68 is carried (Figs. 2 and 5). A detent pawl 69 is pivotally mounted on the plate 68, the pawl being under tension of the leaf spring 70, the spring retaining the pawl in engagement with the teeth of the ratchet wheel 59, to prevent retrogression of the wheel as intermittent motions are imparted to the wheel (Figs.'2 and 5) By means of the slot 66 and'the bolt and nut 67 it is possible to adjust the plate 68 and the pawl 69 to accommodate ratchet wheels of various diameters. The ratchet wheel 59 in the present instance is provided with three hundred and fifty teeth, hence making a hose wherein there are fourteen hundred courses, and the intermittent movements of the wheel, a tooth at a time, causes one course in the hose, and each revolution of the ratchet wheel makes three hundred and fifty courses, rendering it necessary that the ratchet wheel and the pattern wheel (which rotate together) to make four revolutions, producing a hose having fourteen hundred courses therein. The changing of the ratchet wheel to one of larger diameter necessitates changing the number of pins on the pattern wheel, should it be desired to produce a hose having a greater or lesser number of courses. The increasing or decreasing of the number of teeth on the ratchet wheel for producing hose having a greater or lesser number of courses necessitates changing the pattern of the hose insofar as the narrowing thereof is concerned.

In order to impart an intermittent motlon to the ratchet and the pattern wheel, which are fast on the same shaft, as identified b the numeral 58, a support consisting of a b0 1:

70 (Fig. 5), is carried by the lug 54, nuts 71 being mounted on the support or bolt to hold the same rigid. A lever 72 (Fig. 5) 1s pivoted on the head of the support 70 as at 73 and carries a pawl 74, which is'pivotally mounted on the lever at 75, a leaf spring 76- carried at 77 on the lever tensions the pawl 74 to hold it in engagement with the teeth of the ratchet 59 better shown in Figure 5. A limiting abutment 7 8 (Fig. 5) is secured on the upper portion of the left hand upright of the frame 2 and is disposed in the path of the lever-72 to limit the lever 72 in its return movement, after .imparting a single tooth movement to the ratchet 59. A spring 7 9.

(Fig. 5) connected to the lower end of the lever 72 and in turn to a stud screw 80 acts to retain the lever 72 in engagement with the limiting abutment 78. An angle plate 81 (as in Figs. 2, 4 and 5) is secured at 82 to the lever 72, and carries an arm 83, which is disposed to lie in the path of a projecting cam lug 84 on a disc 85, which is keyed or otherwise fastened at 86 on the shaft 3. When the clutch sleeve 14 is moved to operatively connect the gear 4 with the shaft 3, the disc 85 will also rotate one revolution, and each revolution of the disc 85 will cause the projecting cam lug to engage with the arm 83 and thereby tilt the lever 72 in a direction toward the ratchet wheel 59. When this movement is imparted to the lever 72, the pawl 7 4 engages a tooth of the ratchet wheel 59 and imparts to the wheel intermittent motions, each movement being the distance of a tooth, the pin or pattern wheel rotating correspondingly. It will be noted that the lever 72 has an extra opening 88 (Fig. 5), whereby the pawl 74 may be adjusted, that is lowered further down on the lever 72, in order to permit a larger diameter of ratchet to be applied to the shaft 58. This adjust ment of the pawl 74 may be considered as a point of adjustment for a maximum diameter of ratchet wheel with the maximum number of teeth thereon.

\ A bed plate 89 (Fig. ,5) constituting a guide is mounted upon the auxiliary frame 55, and is provided with a dove tail guide 90 longitudinally therein, and operable in the guide 90 is an intermittent movable carriage 91. (Fig. 5). This carriage has mounted thereon a toothed rack 92a (Fig. 5), and carried by the carriage are brackets 92 and 93, and journaled rockably in the brackets is a rocking rod 94 (Figs. 2, 5 and 6). Suitable arms 95 and 96 are secured to the rod 94 and rocked therewith, and mounted upon the arms 95 and 96 in any suitable manner are insulating blocks 97 (Fig. 5).

Suitable switches are carried on the insulating block 97 comprising the contact plates 98 and 99, which are yieldably movable, and the stationary contacts 100 and 101. with which the movable contacts 98 and 99 engage, for the purpose of intermittently closing electric circuits, one circuit for energizing the solenoid magnet intermittently, the

' other circuit to be closed at the completion of the hose (Figs. 2 and 5). I

An abutment plate 102 (Figs. 2 and 5) is secured at 1.03 to the side face of the rack 92a, and a third arm 104 (Fig. 5) is secured to the rocking rod 94 and is located behind an arm of the plate 102 acting to limit the rocking rod in its movement after a pin 40 on the pattern wheel has passed the switch which comprises the movable contact 99 and stationary contact 101. A spring 106 is interposed between the rack 92a an the arm 104;

said spring being fitted within adepression 105 formed in the side face of the rack, and operates to hold the arm against the plate 102. When a pin 40 on the pattern wheel 41 engages with the movable contact 99 and closes the switch, by engaging the contact 99 with the stationary contact 101, the pin 40 having passed the movable contact, the spring 106 having been put under tension, returns the arm 104 again in engagement with the abutment plate 102. Secured at 107 to the bed plate 89 are upstanding brackets 108, 109 and 110 (Figs. 2 and 4), the brackets 108 and 110 having lateral arm 111 and 112, in guides 113 on which a slide bar 114 is mounted. The upstanding bracket 109 has a lateral arm 115 on which a detent dog 116 is pivoted. A similar dog 117 is pivotally mounted on one side of the slide bar 114. These detent dogs 116 and 117 engage with the teeth of the rack 92a, the detent dog 116 acting to prevent retrogression of the rack subsequently after the dog 117 has imparted an intermittent motion to the rack and the attendant. parts carried thereby.

In order that the detent dog 117 (Fig. 2) may impart a step bystep movement to the rack, a cam 118 (Fig. 5) carried by the hub of the ratchet 59 engages with a roller 119 which is carried by an arm 120, which is secured to a lateral projection 121 of the slide bar 114 (Figs. 2 and 5) A spring 122 is connected to a stud 123 on the slide bar 114 and is in turn connected to the stud 124 on the lateral arm 112 of the bracket 110. Thistensioning spring l22 urges the slide bar in a direction toward and retains the roller 119 in engagement with the cam 118, when the cam is in a position to engage with the roller.

A spring 125 (Figs. 2 and 5) connected to a stud 126 (which is carried by an extension 127 of the auxiliary frame 55) is connected to a screw stud 128 and constitutes means to return the carriage in its initial position, when the detent dog 116 is disengaged from the rack. The two dogs 116 and 117 have lateral lugs 129. A second rocking rod 130 (Figs. 2 and 5) is mounted in brackets 131 carried on the rear face of the rack 92a, and a U-shaped lifting rod 132 is fixed to the rocking rod 130, and the elongated ortion of the u-shaped'lifting rod lies un er the lugs 129 of the dogs 116 and 117, the purpose being that when the rocking rod 130 is rocked the U-shaped lifting rod 132 will en ge under the lugs 129 and lift the detent diigs 1'16 and 117 out of engagement with the teeth of i 94 may to the end of its intermittent motions, and when the rack and the carriage reach the limit of its intermittent motion the dogs 116 and 117 are lifted out of engagement with the rack, and at such instance the two rocking rods 94 and 130 rock simultaneously;

To accomplish this simultaneous movement of the two rocking rods, at the limit of the intermittent motion of the rack and the carriage, arms 133 and 134 shown better in Figure 6 are made fast to the rods 94 and 130, there being a link 135 loosely connecting the two arms 133 and 134. This link 135 comprises a turn-buckle 136 (Fig. 6) and two screws 137, the latter loosely engaging in counter-sunk openings 138 (Fig. 6) formed in the arms 133 and 134. It is possible toadjust the turn-buckle to regulate the relative positions of the arms 133 and 134. When the rocking rod 130 is operated, the arm 134 moves with it, and pulls on the link, which in turn actuates the arm 133 and thereb rocks the rod 94, moving the two switches with the rod 94 out of the path of the pins on the pattern wheel. p

Also fast on the rocking rod 130, on its end opposite the arm 134 is a lateral arm 139 (Fig. 2), which is designed to be engaged with by a lug 140- on the patternwheel, im-

parting a lifting movement to the arm 139, rocking the rod 130 and in turn the rod 94 through the medium of the link connection with the arms 133 and 134.

An angle bracket or plate 141 (Figs. 2 and 5) is secured at 142 to the side face of the upstanding bracket or hearing 56, and its lateral part has a slot or recess 143, through which the end ofan L-shaped angleplate 144 (Figs. 2 and 5) passes, so that the end of said angle plate may ride on the lateral part of the bracket 141, until the carriage and its rack returns to its initial position subsequently to the disengagement of the detent dogs from the rack. In other words when the lug 140 on the pattern wheel reaches a position to engage and does engage with the arm 139, the end of the angle plate 144 passes through the opening or slot 143, and the end' of the angle plate then rides upon the lateral part of the bracket 141, until the carriage and its ra ck reaches initial position, then the end of the angle plate will slide off the lateral part of the bracket 141. In Figure 1 of the drawings a start and stop shaft 145 of a full fashion hose knitting machine such as shown diagrammatically on page 46 of the 1920 book entitled Full Fashioned Hose Knitting MachineTextile Machine Works, Reading,

Pa, and this shaft is adapted to carry a plurality of hand wheels, not shown, by which the shaft may be rocked for starting and stopping the full fashion hose knitting machine.

However to automatically stop the full fashion hose knitting machine, there is also nected in circuit with the usual motor, not

shown, but which is the knitting machine.

On the shaft 145 and movable therewith is a rocker 149, the opposite ends of the lateral arm 150 and 151 of which are in position to bean upon the buttons 147 and 148, so that geared to and operates when any one of the hand wheels on the start and stop shaft 145 is grasped and rotated to rock the shaft 145, the arm 150 of the rocker will bear upon the button 147, operating the switch 146 and thereby closing the circuit of the motor. By operating the shaft 145 in a direction opposite the arrow b4, the arm 151 will bear upon the button 148 and again operate the switch and open the circuit with the motor, not shown, and. hence stopping the knitting machine.

A second rocker 152 is loosely mounted upon the start and stop shaft 145, and one of its arms 153 is in a position to engage with a button 148, while its other arm is connected to a plunger rod 154, which is carried by a core 155 of a solenoid 156. This solenoid magnet is connected to a battery 157 by a wire or lead 158, while the other end of the solenoid magnet is connected by a wire or lead 159 to the switch which comprises the movable and stationary contacts 98 and 100, the movable contact of this switch being in turn connected by a wire or lead 160 to the battery 157.

Obviously when a pin 140 on the pattern wheel engages with the movable contact 98 engaging it with the stationary contact 100, a circuit is closed over the wires 158, 159 and 160 energizing the solenoid magnet 156 and drawing the core 155 upwardly through the magnet, and actuating the plunger rod 154 and hence tilting the rocker 152 and causing the arm 153 to depress the button 148 and closing the circuit to a motor not shown which operates the full fashion hose knitting machine. In this manner the knitting machine ceases operations at the completion of a hose. In the operation, the knitting machine is set for the purpose of knitting a number of hose 1 fifty courses of the hose are knitted.

On one face of the pattern wheel there is provided two sets of four annular rows of pins 40, which predetermine the pattern or shape of the hose. These rows of ins are identified as 61, 62, 63 and 64. The rst row com rises, in the present instance, five pins pre etermining five steps of narrowing or shaping of the hose, the remaining portion of this row is blank, during which time the pattern wheel rotates the remaining portion the narrowing mechanism of the full fashion %ose knitting machine ceases to narrow the ose.

The next row on the pattern wheel identified at 62 is blank, and during the revolution of the pattern wheel the knitting of the next three hundred and fifty courses is uniform.

The third row comprises a plurality of pins 63, which are arranged annularly for a distance substantially half the diameterof the pattern wheel, the remaining portion of the row being blank.

The next row 64 consists of a plurality of pins relatively close to each other and disposed a relatively short distance, shorter than the first row and containing substantially twice the number of pins in the row 61. The remaining portion of the row 64 is blank. These blank portions of the rows 61 to 64 inclusive are indicated by dot and dash lines, While the pins are represented by small circles, that is where the pattern Wheel is shown in elevation.

Obviously each time a pin 40 in the row 61 engages with the movable contact 99 and engages said contact with the stationary contact lOl the solenoid magnet 29 is energized, sucking up the core or plunger 30, movin the arm 32 and the notch 36 allowing the c utch pin 33 to engage with the clutch tooth 23 and thereby permitting the clutch collar 22 to rotate with the clutch sleeve 25. When the arm 33 is moved out of engagement with the notch 36 the arm 37 is also moved out of the path of the stop lug 24. When the clutch collar 22 is rotated with the shaft, the a lateral cam lug 43 tilts the lever 46 against the action of its spring, pulling the rod 50 in the direction of the arrow a4 in Figure 1, and thereby actuatin the narrowing mechanism of the full fashion hose knitting machine, thereby causing a narrowing shaping step to the hose. Every time a pin of an one of the rows 61 to 64 on the pattern whee closes a circuit through the solenoid magnet 29, a narrowing or shaping step is caused in the hose being knitted.

As the row of pins 61 pass the switch, the narrowing or shapling steps are substantlally infrequent, and w ere this row 61 is blank the narrowing or shaping step is uniform.

The next row 62 is entirel blank, therefore the three hundredand fty courses in this row are uniform. V

.The third row 63 of pins 40 extend sub stantially one-half the diameter of the pattern wheel and are more frequent than the arrangement in the row 61, while the row 64 is even shorter than the row 61 and the pins are arranged more frequent, therefore the shaping or narrowing of the hose during this course, that 'is for a relativel short distance, is relatively abrupt, and t is portion of the shaping is at a point just above the ankle portion of the hose, the same as in a hose construction in a full fashioned knitting machine described in the book published by the Textile Machine Works, Reading, Pa. The row- 63 determines the approximate shaping of the hose where it conforms to the calf of the leg, while the blank row 62 determines the shaping of the hose from the origin of the calf of the leg to a point adjacent the knee, while the narrowing steps determined by the row 61 shapes the hose to conform to the leg from a point adjacent the thigh to a point approximating a position above the knee and from this point to the knee the remaining blank portion of the row 61 determines the uniform courses. The pattern wheel also carries on its face the pins 40 pins 14% and a master stop pin 140. The pins 140?; stop the machine at predetermined lntervals for inserting different wool or dlfferent color threads. As the pattern wheel revolves the pins 140b in their passage engage with the movable contact 98 and cause it to engage with the stationary contact 100. The solenoid 156 is ener ized pushing the core 154 up against the roc er arm 152 which pushes down on the stop button of the control switch which stops the machine.

The movable contacts 98 and 99 are mounted on the slide 92a which is actuated by the dog 117 which connects the slide bar 114 with the arm 120 and roller 119, which are actuated by the cam 118. The cam 118 is mounted on the shaft 58 with the pattern wheel 41 and ratchet wheel 59, which are advanced a single tooth at one revolution of the shaft 3, which carries cam 84, which actuates pawl 74. Each complete revolution of the pattern wheel and ratchet wheel with the cam 118 mounted on the same shaft, pushes the slide bar 114 which is held by spring tension, back, so that the pawl 117 will engage the next tooth of the slide 92a andmoves the same a single tooth length ahead when 119 slides off the lug of the arm 118. This brings the movable contacts 98 and 99 in line with the pins of each row, which necessarily re eats itself during the operation of the mac ine. The pin 140, as previously stated acts as a master stopfor putting the machine at rest. The clutdh tooth 9 (acting as a member of a clutch which is driving a shaft 3 and clutch sleeve 25) and parts associated therewith are auxiliary mem ers for stopping the whole unit. (Hose narrowing device regulator and stop mechanism.) This is necessary in case of test runs or repairs on the machine, where it is necessary not to stop the machine or have the narrowing mechanism working.

These operatlons and the various steps of cuit or leads 158, 159 and 160 for the purpose of energizing the solenoid magnet 156 and hence actuatin the rocker 152 and the shaft- 145, and there y stopping the machine.
